INTRODUCTION Thank you for purchasing the amazing portable PA system PBM4 SISTEMA. This system is small enough to fit into any airplane's overhead storage compartment yet being flexible and powerful enough to be used for small gigs and professional multimedia presentations. PBM4 SISTEMA includes a 45+45 watt stereo amplifier, a 5-channel mixer, and 2x5" full range speakers. The chassis is made by moulded polypropylene for shock and moisture protection. Your PBM4 SISTEMA is the ideal tool for: Multimedia Presentations, Weddings, Small Church Functions, Gym, Music Rehearsal, Small Gigs, School Functions, and more . Enjoy your PBM4 SISTEMA and make sure to read this Manual carefully before operation! 2.

QUICK START This is the fastest way to get something out from your PBM4 SISTEMA, if you have a keyboard and a microphone. a. Well, there is not really much to say before starting to operate the PBM4 SISTEMA. It includes Mixer, Amplifiers and Speakers, so just put it on a clean table first and make sure that the Power switch on the back panel is on OFF position. b. Turn down the Input Channel Gain Controls and the MAIN and MONITOR controls. c. Keep Input Channel EQ and Master EQ controls in center position. d. Only at this point you can connect the AC cable into an AC socket and you can switch the system ON. e. Now connect a microphone into Channel 1-3 or a Line Instrument into Channel 4. f. Slowly turn up the Input Channel LEVEL Control and then the MAIN Control. g. For an optimal sound reproduction make sure that the -10 and 0 LEDs on the Master LED Meter are blinking. Here you are. It is your first gig with your PBM4 SISTEMA.. 3 HOOK MULTIMEDIA PRESENTATION UP MAIN R LTO BASS MIDDLE HIGH 0 0 0 MONITOR OPERATING 10 0 dB 0 0 -10 PBM4 SISTEMA PHANTOM -30 ON +15dB -15dB - - +10dB OFF +10dB 8 +15dB -15dB 8 +15dB -15dB LEVEL 0 0 HIGH 12KHz 12KHz 0 +15dB -15dB LOW NOISE P 8 +10dB LEVEL LOW NOISE P RE A +10dB LOW NOISE P RE A +15dB - -15dB MAIN POWER OUT +10dB LEVEL RE A M 2 1 3 LINE IN (bal.)

Use the XLR socket to connect a low impedance balanced dynamic microphone or a low level signal. You can also connect a Condenser microphone into the XLR socket (See following about Phantom Power). Use the LINE IN socket to connect a Line Level Instrument such as a keyboard or a drum machine. You can also connect an electric guitar or bass through an option DI Box (Direct Injection Box) 8 SP 2 1 3 LINE IN (bal.) 1 MIC IN (bal.) 2 PHANTOM POWER SWITCH CH 1 When the (2) switch is at ON position, a +15V phantom power will be applied to CH1 through CH3. Only Condenser microphones need Phantom Power, so switch it OFF when you use dynamic microphones. PHANTOM 3 TAPE IN Here you can connect a stereo Line Level via RCA sockets. Usually this stereo channel will be used to connect into the PBM4 SISTEMA with the audio output of a Computer, or a CD Player, iPOD, MP3 player, etc. 4 TAPE OUT 2 ON OFF LEVEL Via these two RCA sockets you can route out the Main Stereo signal usually to a Tape Recorder or DAT Recorder. IN 3 TAPE OUT 4 CH 4 5 LEVEL CONTROL It adjusts the LEVEL of individual channels with a range from to +10dB. 6 CHANNEL EQ Each Input channel has its own 2 bands equalizer with an adjustable range of +/-15 dB. The HIGH control creates a shelving filter that will boost/cut all frequencies above 12 kHz. You can use it to eliminate high frequency noise and hiss (such as those produced by Tape Recorders) or to boost and make crispier the cymbals or certain harmonics of the human voice. The LOW control will create a shelving filter that will boost/cut frequencies below 80 Hz. Use the LOW control to put in evidence Kick Drum or enhance male voice. 5 SP OT L IG 4. 3. CONTROL ELEMENTS HT THREE BANDS MASTER EQ This equalization circuit is inserted before the MAIN level control. You have available 3 controls: BASS, MIDDLE and HIGH. 7 HIGH Use it as a further boost to the overall MIX to get more colour from your program or turn the control down if you want to avoid high frequency noise. 9 8 7 8 MIDDLE This is a unique control designed for a wide variation of middle frequencies. Turn the control down (from center position) and you will make the human voice more warm and smooth while turning the control up will enhance vocal intelligibility. Be careful not to boost these frequencies too much to avoid feedback on microphone inputs. 9 LOW Turn the control down (from center position) if you experience rumble or low frequency noise or turn it up to make the PBM4 SISTEMA sound much bigger than what it is. 10 MONITOR OUT Connect a powered Monitor to this socket or an external Amplifier + Monitor Speaker. You can also use it to connect a pair of Headphones. 11 MAIN POWER OUT You can connect a pair of passive speakers to these Output sockets. In this case, the internal speakers will be disconnected and the 45W x 2 internal amplifier signal will be assigned to these sockets. 11 MAIN POWER OUT MONITOR OUT 10 6 SP OT L IG 4. CONTROL CONTROL ELEMENTS ELEMENTS 3. HT 12 MAIN There is the Main Mix Control adjusting the overall volume assigned to the 2 internal speakers or to the MAIN POWER OUT speakers. 13 MAIN LED METER This 4 segments LED Meter will monitor the volume assigned by the MAIN level control. If the +10 LED flashes, you have reached the limit of the internal 45+45W amplifier and the outgoing signal is approaching distortion. +10 LED should flash only occasionally. If no LED is blinking, it means that the output level is too low, so either you do not hear any music or the signal is too low to the noise level. For optimal functioning LEDs marked -10 and 0 should always be blinking. 14 MONITOR Via this Control, you can adjust the signal Level applied to the MONITOR OUT sockets. 15 OPERATING This LED will blink when your PBM4 SISTEMA is switched ON. REAR PANEL 12 13 14 15 2 16 POWER ON/OFF This switch is used to turn the main power ON/OFF. 17 AC INLET Use it to connect your PBM4 to the main AC with the supplied AC cord. Please check the voltage available in your country and how the voltage for your PBM4 SISTEMA is configured before attempting to connect your PBM4 SISTEMA to the main AC. POWER ON OFF 16 FUSE 2A AC~230V 50/60Hz 17 7 5. INSTALLATION AND CONNECTION Ok, you have got to this point and you are now in the position to successfully operate your PBM4 SISTEMA. However, we advise you to read carefully the following section to be the real master of your own mix. Not paying enough attention to the input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow this procedure for every single channel: 1. Turn down all Input and output gain controls. 2. Connect phantom powered microphones before switching on the +15Volt phantom power switch. 3. Set the output level of your PBM4 SISTEMA or the connected power amplifier at no more than 75%. 4. Now, set the MONITOR level at no more than 50%. In this way you will be able to hear later what you are doing connecting a pair of headphones or a pair of powered studio monitor speakers. 5. Position EQ controls on middle position. 6. Increase the input gain properly for maintaining the good headroom and ideal dynamic range. 7. Depending on the actual application, turn slowly the input and output level controls for obtaining the maximum gain before distortion. 8. Now repeat the same sequence for all input channels. The main LED meter could move up into the red section. In this case you can adjust the overall output level through the MAIN MIX control. Audio Connections You can connect unbalanced equipment to balanced inputs and outputs. Simply follow these schematics.
